2015 AUDI Q3 rims

212 Tire s and wheel s
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this normally also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled rims . If different rims are fit ­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model¢
page 239.
.&_ WARNING
Improperly tig htened or maintained wheel
bolts can become loose ca using loss of
cont ro l, a co llision and serious p ersona l in­
Jury.
- Always keep the wheel bolts and the
threads in t he wheel hubs clea n so the
wheel bolts can tu rn easily and be prop­
erly tigh tened.
- N ever grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- O nly use wheel bo lts that be long to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Alw ays mai nta in the co rrec t tighte ning
tor que fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the veh i- cle is moving.
If the tig
hte ning torq ue is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
105 ft lbs. (140 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changing a wheel, the
torque must be checked as soon as poss i­
ble with a to rque wrenc h - preferab ly by an
a uthorized Aud i dea le r or qualified wor k­
shop.
Low aspect ratio tires
Your A udi is factory -eq uipped w it h low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
t read width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
pa rticularly sen sitive to improp er inflation
pre ssure. It i s therefor e important that low
a spe ct ratio tir es are inflated to the spe cified
pre ssure and that the inflation pre ssure i s
regula rly checked and mainta ined. Tire pre s­
sure s should be checked at lea st once a
month and always befo re a long trip
¢ page 201, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.

Tires with unidirectional tread design
Tires with uni directional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
W hen using a spa re tire w it h a t read patte rn
intended fo r use in a specific direction, p lease
note t he followi ng:
- The di rection of rotation is ma rked by an
ar­
row on the side of the t ire.
- If the s pare tire has to be inst alled in the in ­
correct di rection, use the spare tire only
temporarily since the t ire wi ll not be a ble to
achieve its optimum pe rformance character­
ist ics with regard t o aquaplani ng, noise and
wea r.
- We recommend that you pay particular at­
tent io n to this fact during wet weather and
t h at y ou adjust y our speed to matc h road
co ndi tions .
- Rep lace the flat tire w ith a new one and
have it installed on your ve hicle as soon as
poss ible to restore the handling a dvan tages
of a uni direct io na l ti re.
Notes on wheel changing
Please re ad the inform ation ~ p age 206 , New
tires and repl acing tires and wheels
if you are
goi ng to use a s pare t ire which is different
from the tires on your ve hicle .
A ft er you ch ange a tire:
- Check the tire pressure on the spare imme­
diately after installation .
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as possible by your authorized Audi dealer or
qualified workshop. What do I do now? 223
- With steel and alloy wheel r ims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs. (120 Nm).
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque.
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover .
Until then , drive with extra care and at re­
duced speeds.
